Comparative Chloroplast Genome Study of Zingiber in China Sheds Light on Plastome Characterization and Phylogenetic Relationships.

ABSTRACT:

Background

Zingiber Mill., a morphologically diverse herbaceous perennial genus of Zingiberaceae, is distributed mainly in tropical to warm-temperate Asia. In China, species of Zingiber have crucial medicinal, edible, and horticultural values; however, their phylogenetic relationships remain unclear.

Methods

To address this issue, the complete plastomes of the 29 Zingiber accessions were assembled and characterized. Comparative plastome analysis and phylogenetic analysis were conducted to develop genomic resources and elucidate the intraspecific phylogeny of Zingiber.

Results

The newly reported plastomes ranged from 161,495 to 163,880 bp in length with highly conserved structure. Results of comparative analysis suggested that IR expansions/
